The hammering of poor West Brom was Newcastle's fifth successive Barclays Premiership victory and took them level with sixth-placed Blackburn in the race for European qualification.
Glenn Roeder: "The win keeps us in there, the win keeps us in with a chance. I said to the players yesterday when we discussed West Brom, they would come here today with what I would describe as a 'do-or-die' approach.
"But then I also said 'but don't forget, it's do or die for us. If we don't win, we will probably go out of the European race'. It was do or die for both teams - thankfully, we did the doing."
"I always believe the best policy is to be truthful, and I'd probably say Kieron won't be fit for the last two games. We need to get to the bottom of this problem. We are not going to try to rush him back to play a part next week or a part in the Chelsea game. That would be unfair to Kieron. We need to solve why his hamstrings after playing games tighten up and become strains.
"But as we showed today, if we have to go to war without some of our first-choice players, we have young players who want to come in a fight for the club and wear the shirt, and that's what we will do in the last two games.
"Kieron has probably now finished for the season and it's all about getting to the root of the problem and getting him back for pre-season fit and ready to train."
